BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to pool covers and, more particularly, to an inflatable pool cover for preventing debris from entering a pool while simultaneously preventing fluids and debris from collecting on top of the pool cover and for allowing a user to easily remove the pool cover when desired.

2. Background

A favorite summertime activity enjoyed by millions of American consumers is going to a public or private swimming pool. A great way to beat the summer heat, spending time poolside can help ease the stresses of daily life, leaving one tanned, relaxed, and well rested. For children, aquatic activities are especially popular and long hours are spent splashing in the water and playing spirited games of “water tag” and “Marco Polo” with family and friends.

Because swimming, playing, or simply relaxing by a pool is such an enjoyable way in which to spend free time, many consumers opt to have an in-ground or aboveground swimming pool installed right in their own backyard. In fact, according to the National Pool and Spa Institute, nearly fifteen million households boast a residential swimming pool. Why are residential swimming pools so popular? Perhaps it is because they enable consumers to enjoy a variety of aquatic activities, without ever leaving their home. A practical alternative to transporting a carload full of kids, water toys, snacks, towels, and similar amenities to a local swimming pool, only to find that the pool is overcrowded with users, or in worse case scenario, closed to the public, owning a residential swimming pool allows consumers to step outside their back door and enjoy a quick swim, whenever desired.

Additionally, considering that the cost of constructing a swimming pool, particularly above-ground pools, is very reasonable, many consumers find that installing a residential swimming pool in their backyards is an affordable endeavor.

While there is little dispute that residential swimming pools provide consumers hours of summertime fun, their use is not without drawbacks. During the “off” seasons of autumn, winter and early spring, most swimming pool owners cover their pool with a thick plastic cover.

The usual winterizing procedure for a swimming pool involves cleaning the pool and applying chemicals to keep the water free from algae and bacteria. The chemicals may also include an antifreezing agent to keep the water from freezing with the concomitant expansion of the ice, which could burst the pool walls. Typically, an inflated plastic balloon is placed on the surface of the water and secured in place at the center of the pool. Then, a cover, such as a tarp, is pulled over the inflated balloon. When the tarp is finally manipulated into its final position, it is secured in place by tying or anchoring it to the side and/or the deck of the pool.

Plastic pool covers are practical in that they prevent leaves, branches, snow, and rainwater from entering the pool, creating a soupy green mess, and damaging the interior and operational mechanics of the pool. Unfortunately, because of their very function, removing a pool cover at the start of a summer season can be extremely difficult. As many pool owners would attest, attempting to pull a cover, loaded with broken twigs, soggy leaves, particles of paper, and similar debris, and which is heavily weighted with gallons of rainwater and melted snow, without spilling the contents of the cover into the swimming pool, can be nearly impossible. Requiring the awkward removal of this debris before the cover can be lifted from the pool, preparing a swimming pool for summertime use can be an extreme hassle.

SUMMARY OF THE INVENTION

Accordingly, a need remains for an inflatable pool cover in order to overcome the above-noted shortcomings. The present invention satisfies such a need by providing a pool cover that is convenient and easy to use, is durable, and offers the owners of residential and commercial swimming pools a simple and efficient means of preventing debris from collecting on their pool cover during winter months. Use of the inflatable cover advantageously ensures that the pool remains clean and free of debris. Furthermore, the assembly also prevents heavy rainwater, melted snow, and sleet from collecting on the top of the cover, thus enabling consumers to remove their pool cover in a quick and easy manner. Ideal for use with both aboveground and in-ground swimming pools, the inflatable cover is versatile and serves a variety of useful applications.

The various features of novelty that characterize the invention will be pointed out with particularity in the claims of this application.

The figures generally include various perspective and cross-sectional views showing an inflatable cover, in accordance with the present invention. The assembly of this invention is referred to generally in the figures and is intended to provide an inflatable cover, particularly for pools and hot tubs. It should be understood that the assembly may be used to cover many different types of pools and should not be limited in use to only residential aboveground pools. The inflatable cover described herein can also be used for in-ground and commercial pools, as well as hot tubs, fountains, fishpond, and the like.

Referring to FIGS. 1 and 2, a cover assembly, indicated generally as 10, includes an inflatable, dome-like sheet 13 that is configured to rest atop an existing swimming pool 16. The dome-like sheet 13 has a top layer 20 and a bottom layer 22, creating a single inflatable chamber 25 therebetween. The top layer 20 and bottom layer 22 are connected and sealed only along an outer periphery 26 of both by heat sealing, sonic welding, adhesives, or other conventional techniques. The dome-like sheet 13 is produced from heavy duty, plastic or rubber material, which is well suited for extended periods of outdoor use. The dome-like sheet should be formed from materials selected for their ability to withstand heat, cold, and ultraviolet rays. For a round pool, the dome-like sheet 13 has a substantially circular shape. In a particular embodiment, the cover assembly 10 measures approximately twenty-one feet (21′) in diameter, wherein the inflatable portion of the cover assembly 10 measures approximately twenty feet, two inches (20′2″). Of course, the cover assembly 10 may be produced in a variety of sizes and shapes appropriate for use with various aboveground and in-ground swimming pools, as is obvious to a person of ordinary skill in the art. For example, the cover assembly 10 may be configured for circular, rectangular, kidney, or oval-shaped pools and sized to accommodate pools of various dimensions.

Extending along a perimeter of the cover assembly 10 is a border 28, which may be an extension or the top layer 20, bottom layer 22, or both. Alternatively, the extension 28 may be a separate piece attached about the outer periphery 26. The border 28 is approximately ten inches wide. Of course, other widths for the border 28 can be used as is obvious to a person of ordinary skill in the art. A plurality of openings 31 may be provided around the border 28. Preferably, the openings 31 are equidistantly spaced around the border 28, and more preferably, the openings 31 are spaced approximately every 15-inches. In a preferred embodiment, the openings 31 are circular shaped and may be fitted with grommets for use with a tether or cable 32 for conveniently and effectively securing the cover assembly 10 to the sides of the pool 16. The tether or cable 32 can be threaded into the plurality of openings 31. In some embodiments, the cover assembly 10 is sized and configured to fit over the top edge of a wall of the pool 16. In such embodiment, the cover assembly 10 of the present invention can substitute for a conventional pool cover. In an alternate embodiment, the cover assembly 10 is sized and configured to fit inside the top edge of the pool. In such alternate embodiment, the cover assembly 10 of the present invention is used with a conventional pool cover.

Referring to FIG. 3, at least one air valve 34 a positioned proximal to the outer edge of the dome-like sheet 13. Generally, the air valve 34 would be circular shaped; however, other shapes may be used. Said at least one air valve 34 is connected to an opening 37 in the top layer 20. Air valve 34 can be positioned in a first (open) position and a second (closed) position. In the first (open) position, the air valve 34 provides an opening to enable air to be admitted into chamber 25. In the second (closed) position, the air valve 34 provides a seal to prevent air within the chamber 25 from leaking out of the chamber 25. In some embodiments, a reinforced cover (not shown) may be provided for the air valve 34. The at least one air valve 34 is configured so that it can be attached to an air pump 40 or other appropriate source of air to inflate the cover assembly 10. The at least one air valve 34 is used in conjunction with air pump 40, thus advantageously enabling a user to quickly and easily inflate the cover assembly 10. For example, a standard ShopVac® can be used to inflate the cover assembly 10. In a preferred embodiment, the air pump 40 could be included for sale with the cover assembly, as is obvious to a person of ordinary skill in the art. In some embodiments, the air pump 40 may be electrically operated, powered by a cord or by battery. In other embodiments, the air pump 40 may be manually operated.

In use, the cover assembly 10 is very simple and straightforward to operate. First, the user purchases a cover assembly 10 sized and configured in accordance with the size and shape of their pool or hot tub. After preparing their pool for the winter months by conditioning the water, the user positions the cover assembly 10 so that it rests directly above the pool 16, then attaches a tether or cable 32 around the pool 16 through the openings 31, see FIG. 4. In an embodiment where the cover assembly 10 fits inside the top edge of the pool 16, the user should place a conventional cover over the pool after positioning the cover assembly 10 on the pool 16. Next, using an air pump 40, the user fills the inflatable chamber 25 of the cover assembly 10 with air. Once inflated, the dome-like sheet 13 assumes a convex shape that effectively provides an impenetrable umbrella, which completely shrouds the pool while effectively repelling sticks, leaves, rainwater, and snow, which is essential for preventing debris from collecting on the top surface of the cover assembly 10. After proper installation, the cover assembly 10 is left in place throughout the autumn, winter, and early months of spring, conveniently protecting the pool until the weather is warm enough to prepare the pool for use. After use, the cover assembly 10 is quickly and easily deflated by opening the at least one air valve 34, and the cover assembly 10 is removed and stored away along with other pool accessories, until again needed. If desired, a ShopVac® can be used to remove the air from the cover assembly 10.

In another embodiment shown in FIG. 5, the cover assembly 10 includes a securing assembly 50 for affixing the cover assembly 10 to the ground or other surface on or in which the pool 16 is installed. It is to be understood that the description provided for securing assembly 50 is of a general nature and that multiple, similar assemblies are shown as being used in FIG. 5. Therefore, the description provided for securing assembly 50 is applicable to all such similar assemblies shown in FIG. 5. The securing assembly 50 includes a tie-down member 52 having an anchor device on each end, which on one end connects with dome-like sheet 13 and on the other end connects with a stake or other appropriate ground attachment device 59 in the surface upon which the pool 16 rests. It is contemplated that the connection of tie-down member 52 may or may not be with the border 28 of the dome-like sheet 13.

In a preferred embodiment, one end of the tie-down member 52 is connected to a first anchor device 54. In the current embodiment, the first anchor device 54 may be a tether that is sized and configured to operationally engage with any one of the plurality of openings 31 of border 28. The first anchor device 54 provides a stop for retaining the positioning of the securing assembly 50 relative to the border 28 of dome-like sheet 13. In some embodiments, at least a portion of the tie-down member 52 may also engage through openings 31 to allow the position of the first anchor device 54 to be secured relative to border 28. The other end of the tie-down member 52, opposite the end that is connected to the first anchor device 54, has a second anchor device 56. In the current embodiment, the second anchor 56 comprises a ring, loop, or knot that can be connected to a ground attachment device 59 that can be inserted into the surface upon which the pool 16 rests and provides for the secure positioning of tie-down member 52 relative to that surface.

It is contemplated that the first and second anchor devices 54, 56 may employ various technologies and use various mechanisms to achieve their operational purpose as may be contemplated by those skilled in the art. In the current embodiment, the first and second anchor devices 54, 56 are integrally formed with the respective ends of tie-down member 52. The first and second anchor devices 54, 56 may be a knot, a hook, a toggle, a clasp, or a clip, etc. as may be contemplated by those skilled in the art. In the alternative, either or both of these features may be removed from its connection with its respective end of tie-down member 52. Thus, the current invention contemplates a modular capability that allows the interchanging of different mechanisms and/or technologies for operational use with tie-down member 52.

Referring to FIG. 6, a cover assembly 10 is shown having a dome-like sheet 13 incorporating a skirt 43 that includes a plurality of openings 47 around the periphery of the skirt 43. Preferably, the openings 47 are equidistantly spaced approximately every 15-inches around the skirt 43. The skirt 43 may be an extension or the top layer 20, bottom layer 22, or both. In one embodiment, the skirt 43 is integrally formed with and extends from periphery 26 of the dome-like sheet 13. In the alternative, the skirt 43 may be removably attached to the periphery 26 allowing for the interchanging of different skirts of various sizes and configurations. The mechanisms and technology employed to accomplish the modular interchangeability for the skirt(s) 43 and border 28 may vary as contemplated by those of ordinary skill in the art. It is further contemplated that the skirt 43 may be integral with or modularly connectable with the dome-like sheet 13 directly. The skirt 43 is sized and configured to extend a distance down and to overlap the outside of pool wall 18. In a preferred embodiment, the skirt 43 extends at least 24-inches down the side of the pool wall 18, which provides protection for at least a portion of the pool wall 18. Thus, the skirt 43 may have various dimensions without departing from the scope and spirit of the present invention.

In a preferred embodiment, the skirt 43 positions the plurality of openings 47 relative to the ground and the securing assemblies 50. Preferably, in an installed position, the skirt 43 forms an angle of approximately 45° with the pool wall 18. In the alternative, skirt 43 may be sized and configured to substantially extend to and/or operationally engage with the surface upon which the pool 16 rests. In such an embodiment, the skirt 43 would allow a ground attachment device 59 to secure the skirt 43 to the surface simply, without requiring a tie-down member or other device to operationally connect the skirt 43 with the surface.

As described above, with reference to FIG. 5, the cover assembly 10 includes a securing assembly 50. In a preferred embodiment, the securing assembly 50 includes a tie-down member 52 connected on one end with a first anchor device 54 and on the opposite end with a second anchor device 56. The securing assembly 50 operationally connects with the plurality of openings 47 around the periphery of the skirt 43 on one end and, on the other end, secures to a ground attachment device 59 connected to the surface upon which pool 16 rests. The securing assembly 50 may be formed integrally to or be modularly connectable with the border 28, skirt 43, and/or directly with the dome-like sheet 13.

Tie-down member 52 may be of various design and material, for instance, the tie-down member 52 may be a strap, rope, cable, elastomeric cord, or otherwise, as may be contemplated by those skilled in the art. The tie-down member 52 may be variously sized and configured to accommodate the needs of a user and the needs of the cover assembly 10. For instance, the length of the tie-down member 52 may be varied or the tie-down member 52 may include an adjustment mechanism whereby a user is able to adjust the overall length of the tie-down member 52 and securely affix that length. It is contemplated that the tie-down member 52 may not require the use of the first anchor device 54; instead, the tie-down member 52 may thread through the plurality of openings 31, 47. Further, the tie-down member 52 may be integrally formed with the dome-like sheet 13 and not be required to operationally interact with the plurality of openings. Additionally, the tie-down member 52 may include one or more stops within the body of the member itself. For instance, a cord member may include one or more knots within the body that can operationally be engaged with either one of the anchor devices 54, 56 to secure a position.

The number of securing assemblies 50 employed with any given cover assembly 10 may be determined by the number of openings found in the dome-like sheet 13. It is contemplated that the number of securing assemblies 50 employed with any given cover assembly 10 may be more or less than the total number of openings. In an alternative embodiment, the securing assembly 50 may thread a single tie-down member 52 through one or more of the plurality of openings 31, 47, engaging its anchor device 54 with only one of the openings. It is further contemplated that the ground attachment device 59 embedded in the surface upon which the pool 16 sits can operationally connect with more than one tie-down member 52.

In another alternative embodiment, the skirt 43 may include a weighted outer edge that operationally secures the position of the skirt 43 relative to the pool 16 and/or the surface upon which the pool 16 rests. For instance, the weighted outer edge of the skirt 43 may “hang” at various positions relative to the wall 18 of the pool 16, or the weighted outer edge may rest upon the surface upon which the pool 16 rests. Those skilled in the art will understand that various weighting mechanisms and technologies may be used, such as lead weights enveloped within the outer edge of skirt 43, without departing from the scope and spirit of the current invention. It is contemplated that the weighting mechanisms may be integrally formed with and/or removable from the skirt 43, thereby, allowing for the insertion of the weighting mechanisms into the skirt 43 after the dome-like sheet 13 has been positioned relative to the pool 16. Thus, the outer edge of the skirt 43 may include various constructs that allow the weighting mechanisms to be inserted and removed as contemplated by those skilled in the art.

FIGS. 7 a and 7 b show examples of ground attachment devices 59 according to the present invention. FIG. 7 a shows a simple stake, such as a tent stake, that can be used to connect a securing assembly 50 to the ground. FIG. 7 b shows a heavy-duty stake that can be used in areas expecting windy conditions. Other ground attachment devices, such as pegs, rebar, poles, etc. can be used.

In another embodiment, the securing assembly 50 may not require connection to a ground attachment device 59 for insertion into a surface. For instance, the securing assembly 50 may further include a weighted catch to which the members may connect, whereby the weighted catch itself rests on the surface. The weighted catch may itself be secured to the surface using various mechanisms, devices, and technologies as contemplated by those skilled in the art
